Acrotomophilia

Acrotomophilia is the medical term for the sexual desire of amputees. Someone who has acrotomophilia (in the clinical sense) is sexually attracted to persons with an amputation, and may be unattracted to people without amputations, although some can manage by fantasizing that their partner does have an amputation.

In its most extreme forms, a person my be unable to become aroused or achieve orgasm with anyone who does not have an amputation.
